MINE-CAR BUMPER.

Application filed July 28,

This invention relates to cars and more particularly to cars of the type used in coal mines and industrial plants. I

An object of the invention is to provide an improved bumper for mine cars otthis type. c

' After mine cars have been used for a time there is a tendency tor the side walls to bulge and Frequently, supporting brackets are used, but ditliculty is found in obtaining a satisfactory point of attachment orbase for such brackets, particularly at the ends of the car. i

The present invention has asan object the provision oi a bumper, preferably of integral cast construction, provided with integrally formed side wall braces and with means for morning and supporting wall brackets of conventional type.

A further object of the invention is to provide a buu'iper of this character which may be readily applied to a car and which when applied will suitably brace the walls and thereby materially lengthen the useful life of the ear. e

in the drawings, wherein there are shown certain preferredembodiments of the invention,

form oi mine carprovided with a floor 11 (Fig. 2) having resting thereon andcnteridlug longitudinallyofthe car a metallic draw strap or bar 12. The end of the flooring-is protected by a bumper 13 having atop portion or web 1% and a depending from or apron 151' The under surface of the web 1 1- transv scly channeled by providing the 'htly raised boss 16 for the purpose of re)- c I m-gthe end of the draw bar 12 and the raised section is termed with a plurality oi openings 18, 19 and 20 through which may be passed suitable means serving as part 01" a coupler.

In Figure 2 there is shown an anchorin tongue 21 fastened 1n p'ositionby means or a bolt 22, the tongue having a squared pin extending; into'the opening 20 whereby it is held against rotativc movement. therein. Ribs 2 1' projecting u iwardly from the extension 16 of the bumper section 16 assist in preventing lateral movement of the tongue 21 which may serve as anchoring means for a portion of a coupler.

Adjacentthe ends of the bumper the same is provided with side wall braces 25 which eX'tend upwardly above tl'ieplane of the top web 14 and are adapted to resist any tendency of the side walls to sag or spread apart du'ringuse oi the car. In the form of the invention illustrated in Figures Qand 3 these braces or brace portions are substaiitially vertical and are thus adapted for use v wr' a car having the side wall formation shown in Figure 1. e i

'The braces may be provided with suitable openings 26 to serve as means to secure portions of the side walls as by receiving rivets 27. These same rivets may also serve to att-a'ch wall brackets 28, the lower ends of which rest upon outwardly projecting shoulders 29 extending beyond the braces in the ends of the bumper. V 4 A y 1 It will be noted that the entire bumper is an integral casting and that its simple construction enables it to readily be applied either during manufacture of the car or when repairing a car after use.

Referring to Figure 4, the bumper shown is provided with braces having substantially vertical sections 31 and sections 32 inclined outwardly with respect thereto. AreinforF ing web 38 is formed beneath these sect-ions. This type of braeeis adapted for use with a car similar to that shown in Figure 1 and its i use with a car the side walls of which incline upwardly from the floor at a different angle than in the form of car illustrated in Figure 1. i

In Figures 6, 7 and 8 there is shown a bumper similar to that of the views previously described except that the substantially vertical brace portions, are formed with offset or channel portions 36 for the purpose of providing clearance for side wall bands or straps 37 such as are commonly used in certain types of mine cars.

Moreover, as will be observed, this bumper is provided with the shoulders 38 extending outwardly at the ends of the bumper beyond the braces so that an additional supporting bracket may be readily attached to the bumper and supported by these shoulders if desired. Y I Referring to Figure 9, the bumper shown is identical with thatillustrated in Figures 6, 7 and 8, but the same has associated therewith instead of the side reinforcing band or strap 37 a bracket having lug portion ll extending downwardly into the channel formed between the brace and the car side wall, the bracket being attached to the wall and brace as by the bolts 4-2. 7

Obviously, in the type of bumper as illus trated in Figures 6 and 9, as well as in the form illustrated in Figure 4, the formation of the integral bracesmay be varied to render unnecessary the use of a separate supporting bracket in which event the integral upwardly extending wall brace would be provided as illustrated in Figure 4 with an upper inclined sectlon correspond ng tothe' supporting surface 40 ofthe bracket shown in Figure 9.

It will be understood that, the invention is not limited to the details of the construction described and that it comprehends such modificationsas come within the. scope of the 7 following claims.
